The most striking symptom of infection includes cankers located on the main trunk, branch crotches, scaffold limbs, and older branches.
Diseased trees show vertical orange cankers on the trunk and galls on the lower branches.
Trees exposed to cold in autumn and early spring can develop cankers under the bark of the trunk or branches.
Conidia are produced on cankers and fruit mummies in the tree.
Symptoms that are noticeable on the bole are the cracking of the bark, the formation of cankers, and beech snap.
Stem cankers form from the disease moving systemically through the plant.
Stem cankers develop 1 to 3 years after branches die.
Stem cankers are best treated by pruning out infection as soon as it is noticed.
